More than a hundred drivers were charged with driving while under the influence of drink or drugs by Avon and Somerset police over the festive period.
The Operation Tonic anti-drink and drugs campaign led to 136 people being charged out of a total of 857 who were stopped and given breath tests during December.
Police said the numbers were about what they expected this year as they ran a more intelligence-led operation targeting persistent offenders and venues known for drink and drug driving. The strategy resulted in a higher percentage of drivers who were stopped and breath tested being caught.
Figures for December 1, 2012, to January 1, 2013, showed 314 breath tests were given following collisions – 50 were positive. There were 543 tests not involving collisions, of which 86 were positive.
Of the 556 tests taken by people aged over 25, 72 were positive. The number taken by people under 25 was 301, with 64 being positive.
Police received 20 texts from the public who used a special hotline number to report someone they suspected was drink driving.
